MRI reliably characterizes medial meniscal tears
Studies from Korea and the U.S. show that MR imaging of the knee is a reliable and accurate test for the detection of specific subtypes of medial meniscal tears. MRI could also help identify false-positive injuries of the menisci and avoid unnecessary surgeries.
Dr. So Yeon Lee and colleagues at the Catholic University of Korea reviewed records of 192 patients who underwent arthroscopy and MRI of the knee. They found that T2-weighted imaging provided the most useful sequence for diagnosis of radial tears of the medial meniscal root.
University of Wisconsin researchers led by Dr. Arthur A. De Smet retrospectively assessed 559 patients who underwent knee MR scanning and arthroscopy. The investigators found false-positive MR diagnoses of medial meniscal tears are more common for longitudinal tears than for other tear types, particularly after acute trauma. Both studies appeared in the July issue of the American Journal of Roentgenology.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
